HAIR WAVING HEATER Filed March 30, l933 IN VEN TOR ATTORNEYS Patented Apr. 16, 1935 PATENT OFFICE HAIR WAVING HEATER Ernest 0. Frederics, New York, N. Y., assignor to E. Frederics, Inc., New York, N. Y., a corporation ofew York Application March 30,

12 Claims.

This invention relates to heating devices for use in hair-waving operations and more particularly to heating devices which may be clamped about a winding of hair on a curler.

In general, it is an object of the invention to provide a device of the character indicated which will efficiently and economically serve the purposes for which it is intended, which can be readily manufactured and assembled, and which can be expeditiously, conveniently and safely manipulated. I I a Another object is the provision of a heating device which will eifectively cover a particularly large proportion of the. surface of a winding of hair.

A further object is the provision of a heating device which is readily and effectively .utilizable upon the windings of hair of varying diameters.

Another object is to provide an electrical hairwaving heater of an improved nature and having low electrical requirements.

Other objects of the invention will in partbe obvious and will in part appear hereinafter.

The invention accordingly comprises an article of manufacture possessing the features, properties, and the relation of elements which will be exemplified in the article hereinafter described and the scope of the application of which will be indicated in the claims. e v

For a fuller understanding ofthe nature and objects of the invention reference should behad to the following detailed description taken in connection with the accompanying drawing,,in which: a

Figure 1 is a perspective view of a hair-waving heater embodying the invention; l Fig. 2 is a transverse sectionalview along the line 2-2 in'Fig. '1; Fig. 3 is an end view of the device in position about a winding of hair; I I

Fig. 4 is a similar view of the device in position about a winding of hair of larger diameter;

Fig.5 is a detail view, partly broken away, of theterminal block for the central heating member; and

Fig. 6 is asimilar view of the terminal block of one of the lateral heating members.

"In the waving of hair wound upon a curler as by the croquignole process, it is customary to place against the winding of hair a heating device, such for instance as shown in my co-pending applications, Serial No. 340,095, filed February 15, 1929, and Serial No. 450,894, filed May 9, 1930, wherein constructions utilizing single trough-like heating members are exemplified.

1933, Serial No. 663,517 (01. 219- 24) Heating devices wherein a pair of oppositely disposed heating members is utilized, have also been employed.

Difficulties are present, however, in the use of such types of construction. Among such diiiiculties are the restrictions in the size of the heating members due to the necessity for easy manipulation, which restriction reduces the smoothness in the waving effect, and also requires the use of an excessive voltage for the heating of the electrical heating elements commonly contained therein,the lack of adaptability of such heaters for windings of hair of various sizes, and the inability of such heaters to provide heat substantially uniformlyto the winding of hair. With a view to avoiding the foregoing and other difliculties the present invention contemplates the provision of a heater embodying three or more heater members. By the provision of a multiplicity of heater members, the side members may be readily spread without leaving too great a gap in the'art. .'The heating member ID is carried by arms 12 and I3 forming parts of a metallic plate l4, and the heating member H is carried by arms l5 and I6 forming parts of a metallic plate I1. 'The arms l2, l3, l5 and I6 which are all mounted on a centrally disposed pivot pin l8, and the heating members ill and H are normally forced toward each other by means of coil springs l9 and 20 encircling the pivot pin and each anchored to the outer portion of plates l4 and Il. At their outer ends these plates are provided with manipulating handles of the character exemplified in my said co-pending application Serial No. 450,894., and comprising front and rear plates 2i and 22, respectively, formed of insulating material and spaced from each other throughout the major portion of their extent. Each rear plate 22 is attached to the metallic plate M- or H, as the case may be, only at points, indicated at 23, where it is spaced from the plate 22, and is otherwise spaced from the metallic plate.

The centrally disposed heatingmember 9 is likewise supported from the pivot pin IS in the present instance, arms 24 being provided for this purpose. In order that the heating member 9 may be loosely supported, the openings in the arms 24 which fit over the pivot pins are in the form of slots as indicated at 25 permitting a small inward and outward movement of the heating member 9.

' In order to permit a particularly free circulation of air about the device, openings 26 may be provided in the arms I2, l3, l5 and I6, and openings 21 may be provided in thearms 24.' In order to mount the electrical leads for the device, a tether arm 28 is pivoted on the pin 18. Threaded through the tether arm are leads 29 and 36, one of which extends to the heating member In and the other to the heating member I l. A lead 3| extends from the heating member Ill to the heating member 9, and another lead 32 extends from the heating member H to the heating member 9. A terminal block,-as indicated at 33, and a cover member as shown at 34, are provided for the connections to each lateral heating member, and a terminal block 35 and a cover plate 36 are provided for the central heating member.

'It is to be noted that the adjacent edges-of each lateral heating member and of the central heating member are so inclined that the lateral members have a wedge action on the central heating member when in contact therewithx Fig. 3 shows the exemplified heating device in use upon a winding 31 of hair upon a curler 38; a protectorclip' 39 serving toprotect the scalp of the subject.

Fig. 1 shows the same heating device in place upon a winding of hair 40 having a greater periphery.

Since certain changes may be made in the above article and different embodiments of the invention could be made without departing from the scope thereof, itis intended that allmattercontained in theabove description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense. "It is. also to be understood that the following claims are intended to cover all of the genericand specific features of the invention'herein described, and all statements of the scope of the invention'which, as a matter of language, might be said to fall therebetween. r
